Abstract
Uppfinningen avser justering av kedjespänningenhos en motorsåg (100) vid ett skördaraggregat. Förfarandet innefattar stegen att reglera det första manöverdonet i kedjesågens (100) svängkropp (110) genom hydrauliskt tryck och baserat på detta, förflyttas bladflänsen (120) relativt svängkroppen (110) för att justera kedjespänningen, varvid då spänningen uppnår ett förutbestämt värde, styrs ytterligare ett andra ställdon i svängkroppen, så att bladflänsen ingriper med svängkroppen. Uppfinningen avser vidare en motorsåg och ett skördaraggregat.The invention relates to adjusting the chain tension of a chainsaw (100) at a harvester unit. The method includes the steps of regulating the first actuator in the swing body (110) of the chain saw (100) by hydraulic pressure and based on this, the blade flange (120) is moved relative to the swing body (110) to adjust the chain tension, whereby when the tension reaches a predetermined value, further control a second actuator in the swing body, so that the blade flange engages with the swing body. The invention further relates to a chainsaw and a harvester unit.
